Title: Improvements in or relating to winding mandrels
IPC: B65H75/24
Filed: 1978-10-25
Abstract: This disclosure relates to winding mandrels suitable for use in winding filament-reinforced hollow bodies, eg aircraft engine cowls where a large diameter cross-section is required. The apparatus comprises a rotatable squirrel-cage arrangement having a plurality of spaced longitudinal bars disposed substantially symmetrically around its longitudinal axis, and a plurality of mandrel support brackets carried by the bars which support, in use, segments of an annular or hollow cylindrical segmented outer portion around the squirrel cage arrangement to provide a circumferential winding surface.

Patent GB-2017352-A (GB)
Title: Transducing head servo system
IPC: H04N5/783
Filed: 1979-03-19
Abstract: In recording and reproducing apparatus of the type which utilizes transverse positioning of the transducing head assembly to accurately follow a track during reproducing and, at the completion of the track, to position the head to either play the next adjacent successive track, replay the same track or play another track so that the appropriate special motion effect is achieved, tracking is maintained by applying a small oscillatory motion to the head to cause it to vibrate laterally of the track, examining the resulting modulation of the reproduced signal's envelope to generate a tracking error correction signal and applying this to the head assembly. A reference signal employed in the generation of the error correction signal is automatically phase synchronized in response to the head vibrations to correct errors introduced to the error signal as a result of phase changes introduced to the modulation of the reproduced signal's envelope by effects other than mistracking by the head. The speed of a tape capstan is retroactively controlled. <IMAGE>
Patent GB-2022222-A (GB)
Title: Electric ignition of explosives
IPC: F41A19/63
Filed: 1979-04-27
Abstract: In an ignition system for the firing of a plurality of electrically actuable igniters (16), the ignition leading wire (17) of each igniter is formed from a continuous length of insulated wire connecting its two electrical connection terminals. The leading wire is looped around a transformer core (14) having a movable portion (15) that is opened to admit the loop. A firing cable (12) coupled to a source of electrical firing energy (11) is also looped around the transformer. A plurality of transformer cores can be coupled to a single firing energy source by looping a continuous wire from the source, through each transformer and then back to the source. In an alternate configuration, the igniter leading wires (17) are each loop coupled to a toroidal core which is in turn electromagnetically coupled to a transformer by a single loop of insulated wire looped through the core of the transformer and each toroidal core. The ignition system avoids the need to make wire-to-wire connections in detonator assemblies and the external detonator leading wires may be fully insulated at all times. <IMAGE>

Title: Vehicle braking systems
IPC: B60T13/52
Filed: 1979-05-15
Abstract: A dual circuit braking system includes two separate boosters 8, 9 coupled to a common brake pedal by a lever mechanism 3 for the boosters to be operated simultaneously. If one braking circuit should fail the mechanism causes an actuating load to be applied to the booster of the operative circuit with substantially no increase in lost travel of the pedal. The lever mechanism includes a pivot pin journalled in a locating lever 7 which is pivoted to a fixed housing whereby the pivot axis is capable of some lateral movement which is limited by an end portion 16 of the pivot pin engaging the side of an aperture 17 in the housing through which it passes with a small clearance. A switch 18 mounted on the housing detects lateral displacement of the pivot pin 16 to initiate a warning signal indicating that one circuit has failed. <IMAGE>
